AR Coatings

Laser Facet AR coatings are typically designed for a narrow specific wavelength (such as the L band or the C band). Typical performance for each on InP are shown in the following plot. Other laser facet materials such as GaAs will have a similar performance. AR coatings covering other wavelengths and/or for other laser facet materials are available. In addition, broad band AR coatings are available on special request.
